CNC cutting
1 CNC cutting
In 1958, the British Oxygen Company successfully produced the world's first CNC cutting machine, marking a new era of CNC cutting. Subsequently, developed countries have successively carried out in-depth development and research on the technology, process, related supporting software and equipment of CNC cutting. After more than 40 years of unremitting efforts, thanks to the continuous progress of the computer industry, various types and fully functional series of CNC cutting products have been launched to the market. Nowadays, people can use various cutting methods such as CNC and robot cutting for different workpiece objects; In order to meet the cutting performance and accuracy requirements of various materials, flame, plasma, laser and other cutting processes can be selected to truly provide users with comprehensive problem-solving solutions.
The development and research of CNC cutting technology in China began in the early 1980s, with the maturity and widespread application of microelectronics technology. After more than 20 years of continuous development, gratifying achievements have finally been achieved. At present, the types and specifications of domestically produced CNC cutting products are quite complete, and some of them have approached or reached the level of similar international products in terms of technology, performance, indicators, and functions.
2 CNC flame cutting
2.1 Getting Started
In the mid-1970s, China's shipbuilding industry conducted research on the mathematical smoothing of ship hull lines and computer-aided design programs for the unfolding of curved outer plates in the lofting process of ship construction. The output results of this program system can be used for CNC machining, As a result, the cutting of ship's steel plates no longer requires multiple tedious processes such as full scale layout, sample making, drawing lines on the steel plates, and manual or semi-automatic cutting. As a result, the advantages of using CNC cutting for ship's steel plates are immediately demonstrated. It not only saves labor hours, setting out platform space, and sample materials, but also reduces labor intensity for workers, greatly improving work efficiency. It is in this context that CNC flame cutting machines have begun to enter Chinese shipyards for steel plate cutting and cutting.
2.2 Advantages of CNC flame cutting machines
a. Fully functional and highly automated;
b. Equipped with multiple cutting torches for operation, with long effective cutting time and high production efficiency;
c. Adopting a nesting cutting program improves the utilization rate of steel plates and reduces thermal deformation;
d. Cutting information is easy to prepare, modify, and save;
e. High machining accuracy and good cutting quality;
f. The machine runs stably and reliably, and is easy to operate.
3 CNC plasma cutting
3.1 Overview
Human beings have a history of using plasma arc cutting to cut metal materials for over 40 years, while the application of CNC plasma cutting to China's shipbuilding industry has only been around for nearly 10 years. However, it is not difficult to find that this is a rapidly growing new technology, which has brought tremendous changes to the steel plates of China's shipyards and had an extremely profound impact. To this day, CNC plasma cutting machines have taken over from CNC flame cutting machines and occupy a dominant position in steel plate cutting in shipyards. Moreover, when ordering a new ship, the shipyard has been asked whether it has CNC plasma cutting processing methods
